INVENTOR .Allaert N. ru er ATTORNEY Patented Mar. 8, 1932 PATENT OFFECEALBERT M. KRUGER, OF NEWARK, NEW JERSEY PERPETUAL CALENDAR Applicationfiled March 2 2, 1929. Serial No. 349,229.

This invention relates to improvements in perpetual calendars; and theinvention has reference, more particularly, to a unique and simplearrangement of parts whereby a display of the dates of any given monthmay be obtained in correspondence to the days of the month on which saiddates may fall in any given year.

The invention has for its principal object to provide a perpetualcalendar comprising parts of such construction and cooperativearrangement that the amount of printing reuired is reduced to a minimum,and in which t e parts themselves are reduced to a minimum number.

Another object of this invention is to provide in connection with theperpetual calendar device means for selectively eliminating display ofdate numerals 29, and 31 in connection with any given month in whichsuch dates do not occur.

Other objects of this invention, not at this time more particularlyenumerated, will be clearly understood from the following detaileddescription of the same.

An illustrative embodiment of the novel perpetual calendar madeaccording to this invention is shown in the accompanying drawings, inwhich Fig. 1 is a perspective view of the base member of the calendar,illustrating the mannor in which its parts are arranged to provide aplurality of sections carrying month and day captions, which sectionsmay be selectively folded to disclose any given month.

Fig. 2 is a face view of the calendar with its parts assembled andarranged for use.

Fig. 3 is a plan view of the blank of the date numeral carrier.

Fig. 4 is a plan view of the blank of the cover strip and date numeraleliminator.

Similar characters of reference are employed in all of the abovedescribed views to indicate corresponding parts.

Referring to the drawings, the reference character A indicates a body orbase member upon the opposite sides or faces of which are printed themonth designations together with transverse rows of spaces in which theday of the week designations are displayed.

In the preferred form of body or base member, as shown in the drawings,the same is scored transversely to provide a plurality of sections a, aand a Each section bears on each face thereof two month names withassociated week day designations, as, for example, January and Februaryon one face of section (1. These month and associated week daydesignations are preferably arranged to read from opposite ends of thesection. In the illustrative arrangement, the month and day designationsfor January and February are displayed on one face of section a and themonth and day designations for November and December are displayed inlike manner on the opposite face of section a. On one face of section athe month and day designations for March and April are thus displayed,and on the opposite face of section a the month and day designations forSeptember and October are displayed. On one face of section a the monthand day designations for May and June are displayed, and on the oppositeface of section a the month and day designations for July and August aredisplayed. The sections a, a and a may be selectively folded to exposeany desired face of a given section. It will be understood, however,that the three section arrangement of the base or body member shown inthe drawings and above described is to be considered as illustrative andnot in a limiting sense, since a greater or less number of foldablesections may be employed by printing more or less of the month and daydesignations on the faces thereof, all whereby a display of any givenmonth name may still be selectively attained.

An adjustable date carrying member is provided for selective operativeassociation with a given month and day designation. This date carryingmember comprises a flexible strip or band B upon the face of which areprinted thirteen columns individually corresponding in width to thespaces on the main body or base member A containing week daydesignations. Transverse rows of (late numerals are arranged in saidcolumns as follows :In the seven columns at the right the date numerals,beginning with the top row,

run consecutively and continuously from row to row from 1 to 31, and inthe six columns to the left, beginning with the second row, the datenumerals run consecutively toward the left in each row in reverse order,all as shown in Fig. 3 of the drawings. The date carrying strip or bandB is operatively applied to an exposed section of the body or basemember A by wrapping the strip or band B transversely around the latter,as shown in Fig. 2. The strip or band, as thusapplied to thebody or basemember A, may be moved transversely to adjust the same to the month andday designation of the exposed section of said body or base member A insuch manner as to bring the date numeral 1 into register with the daydesignation of the displayed month on which the first of the monthoccurs; and owing to the described arrangement of the columns and rowsof date numerals on the strip or band B, the date numerals will thereupon be properly arranged in consecutive order so as to properlycorrespond to the days of the respective weeks of the displayed month.The free ends of the strip or band B may be folded around the rear faceof the section of the body or base member A to which it is applied, andthen the remaining sections of said body or base member A may be foldeddown over the infolded ends of the strip or band B; or, if desired, saidstrip or band B may have its ends joined to form a continuous band orbelt which maybe arranged to encircle either the given displayed sectionof the body or base member A or all of said sections of the latter whenthey are folded together; in either casethe date carrying strip or bandwill be transversely movable around the body or base member A so as tobe capable of adjustment to register the date numerals in properrelation to the week day designations of the displayed month.

If desired, the body or base member sections may be provided, adjacentto their respective ends, with perforationsE, certain of which willregistertogether when said sections are brought into selected foldedrelation, so that a combined tie and suspension cord F may be threadedtherethrough to both retain the sections in the selected foldedarrangement and the associated parts in place, whileat the same timeaffording a convenient means for suspending the calendar for .disnothernovel feature of this invention resides in the provision of means toeliminate dates from the display which are not included in a given monthselected for such display. This means comprises a transverse endlesscover band C having at its upper margin an upwardly projecting tabD of awidth equivalent to the width of three of the date numeral columns ofthe strip or band B. After the body or base member A and date carryingstrip or band B have beenassembled together and relatively adjusted, ifthe displayed month has less than 31 days, the cover band C, which isapplied in encircling relation about the body or base member and stripor band B as assembled together, is adjusted so as to position the tab Dover such dates as maybe desired to be. concealed and thus eliminatedfrom the calendar display of any given month; all of which will bereadily understood from an inspection of Fig. 2 of the drawings. Thecover strip G provides a further advantage in that it furnishes anadditional means for retainin the sections of the body or base member 1Ain selected folded arrangement, and also retains the date carrying stripor band in operative assembled relation to the body or base member, andin its adjusted relation to the latter.

The novel perpetual calendar, embodying the principles of'this inventionas above set forth, may have its parts made of any suit able material.For example, the body or base member A may be made of comparativelystiff paper, cardboard, pyrox ylin, sheet metal or other material, whilethe date car rier strip" or band B and the cover band C may be made of aflexible material such as paper, textile fabric, pyroxylin, leather, orthe like.

From the above description it will be obvious that this inventionprovides a novel construction and arrangement of associated partsadapted to. provide, a perpetual calendar, and one in which the partsare reduced to a minimum number, and in which the re- 1.

quirement of printed matter is also reduced to a minimum. Furthermore,the construction and arrangement is capable of quick, easy and simplemanipulation to the end that any given month in the calendaryear may bebrought into display positon with properly associated date numerals atwill.

Having thus described by, invention, I claim 1. In a device of the kinddescribed, a base member foldable transversely at two points to dividethe same into three sections, each face of each section carrying twomonth designations and associated week day designations, and adatenumeral carrying strlp adapted to be disposed around said base memberinjassocia tion with a given selected and displayed month designationand associated week day designations and in transversely adjustablerelation thereto to, bring the exposed date numerals inpropercorrelation to the week day designations of the displayed month, andmeans cooperative with said carrying strip to conceal certain datenumerals. thereof when desired.

2. In a device of the kind described, a base member comprising threeconnected sections foldable into superimposed relation andjprovidedontheir faces with associated month and week day designations, saidsections being foldable to dispose a given face of any single section inoutwardly facing display position, a date numeral carrying strip adaptedto be disposed transversely of said base 5 member in association with agiven selected month and week day designation of an outwardly facingsection thereof, said carrying strip having thirteen columns of datenumerals so arranged that the seven right hand columns bear transverserows of numerals running consecutively from row to row from 1 to 31 andsiX left hand columns having date numerals running consecutively to theleft in each row in reverse order beginning with 35 the second row, saidcarrying strip being transversely adjustable to bring exposed datenumerals in proper correlation to the week day designations of thedisplayed month, and a cover strip superimposed over and about 52 saidassembled base member and date numeral carrying strip in adjustablerelation thereto, said cover strip having a tab projecting therefrom andmovable therewith to cover and conceal certain date numerals of 5 saidcarrying strip when desired, said tab having a width equivalent to thewidth of three date numeral columns.

In testimony that I claim the invention set forth above I have hereuntoset my hand this 539 14th day of March, 1929.
